I don't think they're necessarily intended to be a direct replacement for a car/van. I've got a friend who works for VOK, who make something very similar. The people/companies who buy those buy them as a cargo cycle that's more accessible/comfortable/easier to ride than a 2 wheeled equivalent, such as a Bullitt or an Urban Arrow. The people that ride them generally aren't "cyclists" but people who ride bikes if that makes sense. They don't want to spend all day trying to balance something that weighs 200+kg in the rain.
Obviously more traditional cargo bikes in themselves are a replacement for a car/van...
